Clearest Scanning Sonar on the Water

Garmin DownVü™ scanning sonar gives you a nearly photographic image of what passes down to 750-feet below your boat. You clearly see structure, submerged objects and fish! Traditional Garmin HD-ID sonar and DownVü scanning sonar are combined into one transducer. The echoMAP 45dv also includes sonar-recording capability that coordinates the timing of the sonar return with your boat's position and saves digital information for playback on a computer using free HomePort™ planning software. Use the User Data Sharing Cable to share waypoints and routes between multiple devices.

Heading and Position Refreshed 5 Times per Second

Fast, responsive 5 Hz GPS/GLONASS refreshes your position and heading 5 times each second to make your movement on the screen more fluid. It makes dropping up to 5,000 accurate waypoints and finding your way back to your secret fishing hot spots quick and easy.

Take Your echoMAP with You

When you’re off the water, it’s easy to keep your echoMAP safe and secure. You don’t have to mess with plugging and unplugging wires from the unit because the cords plug directly into the mount. This allows you to quickly install and remove your echoMAP from power and the mount.
